Why Is It Saying 'Failed to Read Sector' When I Clone My Hard Drive?

Here's the thing, I bought a new 1 TB hard drive for my computer, and I was trying to move everything from my old 500 GB drive to this new one by using an EaseUS tool. However, when it reaches 100% it shows 'failed to read sector.' And there's nothing on the new drive. How can I fix this? Appreciate for any help!

"Failed to read sectors" occurs when there are bad sectors on your hard drive, which can lead to the failure of the disk cloning process. Thus, you should scan for bad sectors and repair them first before cloning a hard drive.

Fortunately, EaseUS Partition Master itself can help. It offers two free features, Surface Test and Check File System, to help users detect and fix disk errors automatically.

You can follow the guide below to overcome bad sectors:

Step 1. Connect the faulty hard drive to your computer and launch EaseUS Partition Master.

Step 2. Right-click on that disk and run "Surface Test" to check for bad sectors.

Step 3. If found, perform the "Check File System" for the target partition to repair these bad sectors and corrupted system files.

After this, you will be able to successfully clone the hard drive. Go on and give it a try.
